Use-after-free vulnerability in the abstract file-descriptor handling interface in the cupsdDoSelect function in scheduler/select.c in the scheduler in cupsd in CUPS 1.3.7 and 1.3.10 allows remote attackers to cause a denial of service (daemon crash or hang) via a client disconnection during listing of a large number of print jobs, related to improperly maintaining a reference count. NOTE: some of these details are obtained from third party information.

The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2009-1595 advisory.

    - Applied patch to fix CVE-2009-3553 (bug #530111, STR #3200).

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Updated cups packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

[Updated 12th January 2010] The packages list in this erratum has been updated to include missing i386 packages for Red Hat Enterprise Linux Desktop and RHEL Desktop Workstation.

The Common UNIX Printing System (CUPS) provides a portable printing layer for UNIX operating systems.

A use-after-free flaw was found in the way CUPS handled references in its file descriptors-handling interface. A remote attacker could, in a specially crafted way, query for the list of current print jobs for a specific printer, leading to a denial of service (cupsd crash).
(CVE-2009-3553)

Several cross-site scripting (XSS) flaws were found in the way the CUPS web server interface processed HTML form content. If a remote attacker could trick a local user who is logged into the CUPS web interface into visiting a specially crafted HTML page, the attacker could retrieve and potentially modify confidential CUPS administration data. (CVE-2009-2820)

Red Hat would like to thank Aaron Sigel of Apple Product Security for responsibly reporting the CVE-2009-2820 issue.

Users of cups are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the update, the cupsd daemon will be restarted automatically.

CVE-2010-0302 cups Incomplete fix for CVE-2009-3553

It was discovered that the cups 1.3.7-11.el5_4.4 security update did not fully correct the use-after-free flaw in the way CUPS handled references in its file descriptors-handling interface. A remote attacker could send specially crafted queries to the CUPS server, causing it to crash. (CVE-2010-0302)

After installing the update, the cupsd daemon will be restarted automatically.

The remote host is affected by the vulnerability described in GLSA-201207-10 (CUPS: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in CUPS. Please review the       CVE identifiers referenced below for details.
  Impact :

    A remote attacker may be able to execute arbitrary code using specially       crafted streams, IPP requests or files, or cause a Denial of Service       (daemon crash or hang). A local attacker may be able to gain escalated       privileges or overwrite arbitrary files. Furthermore, a remote attacker       may be able to obtain sensitive information from the CUPS process or       hijack a CUPS administrator authentication request.
  Workaround :

    There is no known workaround at this time.

Several vulnerabilities have been discovered in the Common UNIX Printing System :

  - CVE-2008-5183     A NULL pointer dereference in RSS job completion     notifications could lead to denial of service.

  - CVE-2009-3553     It was discovered that incorrect file descriptor     handling could lead to denial of service.

  - CVE-2010-0540     A cross-site request forgery vulnerability was     discovered in the web interface.

  - CVE-2010-0542     Incorrect memory management in the filter subsystem     could lead to denial of service.

  - CVE-2010-1748     Information disclosure in the web interface.

  - CVE-2010-2431     Emmanuel Bouillon discovered a symlink vulnerability in     handling of cache files.

  - CVE-2010-2432     Denial of service in the authentication code.

  - CVE-2010-2941     Incorrect memory management in the IPP code could lead     to denial of service or the execution of arbitrary code.

This update addresses a denial of service security issue (CVE-2010-0302) as well as fixing several other small problems: * classes.conf is now updated when a class member is deleted. * the usermode dependency has been removed. * the udev rules are now installed in the correct location. * cups-config now has no multilib conflict. * the ipp backend now clears the printer status on completion. * cupsGetNamedDest() is no longer confused by old configuration files. * the scheduler no longer treats SIGPIPE as a filter error. * the gcrypt threading patch has been reverted. * the package no longer owns filesystem-owned directories.

According to its banner, the version of CUPS installed on the remote host is earlier than 1.4.3.  Such versions are affected by several vulnerabilities : 

  - A pointer use-after-free vulnerability exists in the abstract file descriptor handling code in the 'cupsdDoSelect' function in scheduler/select.c.  A remote attacker may be able to leverage this to hang or crash the cupsd daemon by disconnecting while receiving a listing with a large number of print jobs. (STR #3200)

  - The lppasswd utility, when its setuid bit is enabled, allows a local user to escalate his or her privileges because it uses an environment variable to override CUPS' default directories and determine the location of a file with localized message strings. (STR #3482)

Multiple vulnerabilities has been found and corrected in cups :

CUPS in does not properly handle (1) HTTP headers and (2) HTML templates, which allows remote attackers to conduct cross-site scripting (XSS) attacks and HTTP response splitting attacks via vectors related to (a) the product's web interface, (b) the configuration of the print system, and (c) the titles of printed jobs (CVE-2009-2820).

Use-after-free vulnerability in the abstract file-descriptor handling interface in the cupsdDoSelect function in scheduler/select.c in the scheduler in cupsd in CUPS 1.3.7 and 1.3.10 allows remote attackers to cause a denial of service (daemon crash or hang) via a client disconnection during listing of a large number of print jobs, related to improperly maintaining a reference count. NOTE: some of these details are obtained from third-party information (CVE-2009-3553).

Use-after-free vulnerability in the abstract file-descriptor handling interface in the cupsdDoSelect function in scheduler/select.c in the scheduler in cupsd in CUPS 1.3.7, 1.3.9, 1.3.10, and 1.4.1, when kqueue or epoll is used, allows remote attackers to cause a denial of service (daemon crash or hang) via a client disconnection during listing of a large number of print jobs, related to improperly maintaining a reference count. NOTE: some of these details are obtained from third-party information. NOTE: this vulnerability exists because of an incomplete fix for CVE-2009-3553 (CVE-2010-0302).

The _cupsGetlang function, as used by lppasswd.c in lppasswd in CUPS 1.2.2, 1.3.7, 1.3.9, and 1.4.1, relies on an environment variable to determine the file that provides localized message strings, which allows local users to gain privileges via a file that contains crafted localization data with format string specifiers (CVE-2010-0393).

The updated packages have been patched to correct these issues.

Update :

Packages for Mandriva Linux 2010.0 was missing with MDVSA-2010:073.
This advisory provides packages for 2010.0 as well.

lppasswd when running setuid or setgid still honors environment variables that specify the location of message files. Local attackers could exploit that to gather information by using crafted format strings. (CVE-2010-0393)

The previous fix for a use-after-free vulnerability (CVE-2009-3553) was incomplete. (CVE-2010-0302)
